### 3. The set_values() Method

In any interesting widget, the set_values() method will probably do something (but it doesn't in Trivial.c). The code below can be considered boilerplate; you should probably base a subclass's set_values() method on this code. Note especially the region reserved for setting class specific instance variables.

    static Boolean
    set_values(Widget old,
               Widget request,
               Widget new,
               ArgList args,
               Cardinal *num_args)
    {
        Boolean refresh_needed = False;

    !    BB_InSetValues(new) = True;!
        /* do any class specific stuff HERE */
    !    BB_InSetValues(new) = False;!

    !    if (refresh_needed && (XtClass(new) == xmTrivialWidgetClass))
        {
            _XmBulletinBoardSizeUpdate(new);
            return False;
        }!
        return refresh_needed;
    }
